Tongue Pressure Profile Training for Dysphagia Post Stroke
In Brief
A Phase 2 clinical trial evaluating Tongue Pressure Profile Training and Tongue-Pressure Strength-and-Accuracy Training for Dysphagia. Completed, enrolled 14 participants across 1 site.
Detailed Summary
People with swallowing impairment experience particular difficulty swallowing thin liquids safely; the fast flow of liquids makes them difficult to control. The tongue plays a critical role in containing liquids in the mouth, channeling the direction of their flow towards the pharynx (throat) and controlling their flow along that channel. The investigators are engaged in a program of research to better understand tongue function in swallowing, particularly with respect to controlling the flow of liquids. In this study the investigators will compare two different tongue-pressure resistance training protocols, to determine whether a protocol that emphasizes strength-and-accuracy or one that emphasizes pressure timing work better for improving liquid flow control in swallowing.
Study Details
Timeline
Interventions
60 tongue-pressure tasks per session, emphasizing control of the slope of tongue pressure release, informed by biofeedback. Pressures will be measured using a hand-held oral manometer (Iowa Oral Performance Instrument) with signals displayed on a computer.
60 tongue-pressure tasks per session, emphasizing maximum effort strength tasks and accuracy targets within 20-95% of each patient's maximum, informed by biofeedback. Pressures will be measured using a hand-held oral manometer (Iowa Oral Performance Instrument) with amplitude output in kiloPascals displayed on an LCD screen.
